This sound is based on the horror atmosphere of Phasmophobia, the co-op ghost hunting game released in 2020. Audio cues like heavy heartbeat, eerie breathing and ghostly groans became familiar to players through investigations, hunts and close encounters. Short clips of those sounds spread through gaming edits, livestream highlights and horror memes because they communicate danger immediately, even without visuals. It remains popular because a few seconds of audio can make any scene feel haunted, panicked or on the verge of a jump scare.
